Application filed February 15, 1909. serial in. 4mm;

I "is fit; described .in' the following specification, of which the accompanying drawings form a part, iifi fwhich the gparate parts are designatedgbfjthe same New York and State of New York, have in erenco characters'in each-of'the. views, vented certain new and useful Improve: *and-inwhich- -a F. rel is' a plan viewof -one side of my To all evhom it'may concern: Be it known that I, W'ILLIAM Po'rrniz, a citizen of the United States of America,-

lowing is a speci cation such as will enable. those skilled in the art to which it apper tains to make and use the same.

My invention relates to gagesfor .the use of carpenters and others'in laying out work, setting of hardware, etc, and the] object,- thereof is to provide such a-devioe whereby gage marks maybe madeeither IfrOm the'; body or from the end of the device a further object being to provide means .whereb umsaid gage marks will beidentical ii -a justment in the normal use of the device, re gardless of the degree of adjustment eithcr marking point"; a further object be {*In, the drawings forming aT-pa-rt oflflgis appl cation Iv have shown a base a provided 'thereon'by' means 'of headsfb i-Figsal and'G iii-slots b and secured 1n the base operatirg in special uses ofthe device, said marking turned guide 6 at the outer end thereof nd meat of either, thereby adaptingfthe device ylaw- 1S iS iYS F i'g 1';in=s10ts b, and; to the settin" of doors 'wherei'nspa'ce isfi ad d o m e In e' thflme e tension desired there etween and the-etc" thereof sc e ly' s n in Figs-ssaid block jndfplate being providedwith registering notches" b Fig. 4. serving. as anindexlto; the normal positlonwof the'iisai'd', block, and,

adapting the device to mortisingysetting of lock-plates, flush-plates,.and the like; a' furtherobject being to provide guides for the said points whereby, in the use of "the device, the tipping common to gages, now. in use is' prevented; a further object being to provide means for adjusting t-heprimary points, with relation to their guides,- to comdifference of'adjuetn entof the two primary points, when such use is Clt3S1I6(l;"fl, further gage to determine the: depthf-of. af-inortise,

is intended and which is comparatively in- ,on the line 5+5 of Fig. 3; and Fig. 6. is a; section taken on the line 6' 6 Of'F lg-. ;12

{with an extensionct and. havin arabbet-o jF-ig'rd onone edge thereof, a p ate b being adapted @to' slide on said base; being heldhaving a block b" adjustably securedtheretm;

rabbet, or other/cuts intended for ythef re invention; Fi 2 is'a plancview of the other 1 .s de thereof, ig. 3 is 'a' view similar to Fig. 2, but with the parts in difierentpositions,

a, said plate being provided with anuppractice, the block b arranged in absolute register with the edge of the extension a at which time the point is the same distance from'the guide I) as is the 'point'b from the rabbet a regardless of the degree of movement of the bar 0 over serves as a guide, said guides preventing of the device in the operation of marking because of long bearing resulting from the width of the said plate and of the .base, and I may'use either the body or the end of my device for the marking guide .according'to the character of the, work be-' ing 0 erated upon.

7 If it is desired to mortise, either or both of the carriers :5 and d may be reversed in their channels, thus bringing the supplemental points (1 and d?" into operative position and permitting a double mark in either position of the device, said carriers being markings of. parallel lines of different dis tancestherebetween or-o'f the same distance, as desired, according to necessity and if the width of the saiddouble mark be greater than the adjustability of the carriers,-said carriers may be reversed end for end and thus increase the width between the fixed points and the points carried by said ca'r rie'rs, If, however, itis desired weave: the

mark produced by the point 0 more distant fromits guide than is the point 0 from its ide, the screws b are turned and the lock]; moves the plate and guide 6 away from the primary point c without changing the relationship of the point 0' with its guide, this operation being necessary in the setting ofdoors whereby a space results between the door and the door stops and producing acorresponding difference in the setting of the lock striking plate, the degree of said door clearance being visible .on the device by the difference between the block b and the extension (1 as clearly illustrated in F 1v and 5, not only the primary points being operable in this way but also the supplemental points when double marking is desired, and, by means ofthis difference in adjustability of the primary points, a uniform'set-ting of the door hinges results by usingthe point- 0 and a uniform setting of the lock plates in the doors by using the point 0, the former being also employed in setting the lock striking plates, for a great number of doors.

In the original assembling of my device, the notches b Fig. at register with each other but, if through long use, accident, improper poirtt' sharpening, or for any cause, my device should get out of-true, the block plate slidable on said base and having desired, or different, according to the exigencies, and I may move the bar 0 mto any position without altering the relationship of the marking points with the corresponding guides, but this relationship may be altered at any time by moving one of said points away from its guide, or toward it, without changing the relationship of the other gulde and its point andig the degree of change in such point relationship is clearly read upon the device and either a single or a double mark may be ma de from either of said guides, of any degree of single or double adjustment. locked n the desired positions by means of the screws d and d and thus enabling two.

tionship with each other, whereas the guides 11*v and a are movable toward or from each other and thus changing their relationshipv but the relationship of the points with the guides is positive, regardless of the movement of the bar carrying the points.

Having fully described. my invention,

.what I claim as new and desire to secure by Letters Patent, is-' l. A device of the class plate slidable on said base and having an end guide thereon, a bar slidable on said base and having two markingpoints thereon, the distance between the points and corresponding guides being identical in any position of said bar while the plate and base remain fixed in respect to'each other.

2. A'device of the class described, comprising a base having a guide thereon, a an end guide thereon, a barslidable on said base and having two marking points thereon, the distance between the points and corresponding guides being normally identical in any position. of said bar, and means for adjusting said end guide with relation-to its marking point while the plate and base remain fixed in respect to each other.

described, comprising a base having a guide thereon, a

3. A device of the class described, comprising a base, having a rabbet guide thereon, a plate slidable on said base and having an end guide thereon, a bar slidable on said base and'having two marking points thereon, the distance between the points ancfcor-j rising a base having a rabbet guide on said ase, an adjustable plate thereon having an end guide, a bar provided with a marking point for each of said guides adjustable in said base and supplemental marking points adapted to be brought into operative position and operate in conjunction with said first named points.

- A device of the class described, comprising a base having a guide thereon, a plate slidable on said base-and having an end guide thereon, saidbase having an extension and said slide having" a block in normal juxtaposition, means for adjustablv moving said plate in said base, the degree of said movement being indicated by said extension and slide positions, and a bar slidable on said base and having two marking points thereon, one for each of said guides;

In testimony that I claim the foregoing-as my invention I have signed my name in presence of the subscribing witnesses this 11th day of February 1909.
